GLASS-WORKING MAQEIId'ERY.

Application fled September 6, 1834. Serial No. 738,358.

Our present invention relates to methods and means for working glass into manufactured articles, and particularly to methods and means for making and blowing articles of hollow glassware. f

. In the'manufacture of a glass .vessel comprising a main body and a smaller chamber' connecting therewith I find it expeditious to form these parts separately and then fuse them together to form a large chamber andh the smaller chamber connecting therewit v v It is therefore an objectof our invention to provide method and ap aratus for working the two glass parts to them together to form an article of the character described.

It-is of course to be understood, however, v

that the methods and apparatus of our in-.

- wention are applicable generally in the arts.

In the' drawings iforminglp'art of this 'application: I Fig. 1 is aside elevation view of a ma-' chine for splicing a glass tube onto another glass tube a an angle thereto with means "for clamping and positioning with respect to said second tube a wire sealed into said first tube at its end when for instance said machine is used for anode forms onto a tube for a mercury vapor lamp, s

Fig. 2 is a front elevation view of the ma= chine of Fig.1, v I I Fig. 3 is a front elevation view'ofa gas Fig. 4 is a sideelevation. view of the-torch of Fig.3,

' Fig. is avertical sectional view inel'evation 'of'the clamping meansof-Fig. 1 inthe closed position showing ;means for closing and opening the same, I

Fig. 6 isa vertical sectional vieva similar to'Fig. 5 gwlth'the clamping means open.

in the drawings the table 1 supports the standard 2' havin -the"-'arm '3 projecting therefrom iorwardly at\ its upper end At its forward end said arm 3 supports the block 4 having slidably and rotatably mounted therethrough vertical hollow cylinder 5 through which in turn is "slidably mounted the hollow shaft or spindle 6. At the upper end of cylinder 5 is mounted the annuiarly grooved double flange member 10. Slidably mounted on said clinder 5 between member 10 and block 4 is mounted the pulley 11 which drives said cylinder 5 through a sliding key and keyway arrangement not shown-but-well known and common in the art. The member 12 fixed to the top of. said arm 3 and having an extension 13 projecting' over said pulley 11 serves with the upper end' of block 4 tolimit the movement of said pulley vertically. At the lower end of cylinder 5 is mounted the flan e 15 concentrically therewith which has ormed on its upper surface the annular channel 16-which connects with the ipes 17 mounted horizontally one on eacii side of said flange 15. Said pipes 17 ,carr at their outer extremities pipes 18 whic therethrough said channel 16 and carry" at their lower ends the hollow fire members 20. Each of said fire members20 comprises an inverted U shaped member such as a casting which has-a cavity formed therein and, extending substantially throughout its length,

said cavity communicates with the outside through an o ening at the middle ofthe U upwardly an also near the ends oi the legs at the inner lateral surfaces thereof. Through said upward opening-member 21 communicates with the pipe 18. Through said leg openings the cavity communicates with the hollow block 22 which ispivoted between the legs of the U by means of the connect therewith and screws .23.- The cavity 24in said member 21 exteuds'cross sectionally' to provide for communication betweenit and the cavity 21 in difierent positions of said member 2l as it is moved on said screws 23. Extending downwardly and laterally from said member 21 are mounted the fire nozzles 25 which communicate with said cavity 24 and consequently with: said channel 16. About said cylinder 5 between head 4 and flange 15 is 'movably"mounted 'the annular member 27 which rests on said flange 15 and has formed in itsilowe'r, surface the channel 28 which registerswithchannel "16. The rods 30 fixed to the upper side of said ring 27 extend upwardly and fit slidably into the vertical holes 31- formed in saidhead i and serve to prevent rotation of; said ring 27. By rotated movement of said vflange 15 the compression springs 32 mounted about said rods 30 and pressing against said head 4 and said ring 27 serge to hold' said ring 27 against said 'flange15 to thereby secure a gas tight joint therebetween. Mounted to said head 27 and communicating with saidchannel 28 is one which is connected to the pi e 36 which is in suppl cy in ries at its forward end the fork 41 which turn connected to a suitab e source of gas On said arm 3 and back of said er 5 is pivoted the arm 40 which carcarries .at each of its tips pin members 42 which pro'ect one on either side into the channel 0 member 10 and have mounted therein the roller member 43. Said arm,40'

ivot to the ,lever- 46 is connected at its wh1ch serves as a ban e for raising and lowering the end of said arm. 40 and thereby" for upperpro e'ctions 'of' which converge at a raising and lowering said cylinder 5. The annular channel member 10 into which said pin members 42 engage (provide actuating engagement between sai arm-'40 and said sleeve 5, when *said sleeve 5 is rotated by,

means of the pulley 11 as hereinafter more fully described. Also fixed to said arm 40 at its pivot and extending backwardly is the arm 49 whichcarries at its outer end the counter weight 50 whi'ch tends to hold said cylinder 5 and thereby said burner members 20 at an upper limit of vertical movement.

The lever 45 isconneeted to the arm 56 which extends backwardly and upwardly and has formed therein at its outer end the .longitudinal slot 57. Said lever 45 and arm 56 are pivoted at their juncture on said arm 3. Above said arm-40 is mounted the lever 58 which is pivoted between its ends at a and 56v and onthe bracket member 59 car-,

ried by said standard 2. At its forward end said arm 58 carries the fork 62 which stradof said fork beingitself formed into a and straddli each side-of said shaft 6. 4

I Said hollow shaft 6 carriesat its upper 4 end member k 71 screwed thereto which in turncarries a post 72 projecting upwardly dles the upper end of said shaft 6, each leg:

for

and forwardly of the axis of said shaft 6- "and havin pivoted thereto by, bolt 71 the lever 73 w ich extends over and across the center of the endbfthe shaft 6 and terminates at a little distance therebeyond. For depressing said lever 73 the belly crank 75 is mounted at the handleend'of the handle lever 45 and is connected to said lever 73 by means of a chain or thong 76 which passesover pulleys 77 and 78 mounted .on standard 79 at the pivoted end of handle lever 45 and over the pulley 80 mounted below the end of 16:}61'73 and on the lever 58 near its forked en Said hollow shaft 6 carries at its lower end the annular cap 85. Within said shaft 6 is slidably mounted the hollow shaft 86 which terminates at its lower end within said shaft 6 and has its upper end normally extending'beyond theupper limit of said shaft 6 being held in such .a position by the compression spring 87 mounted within said shaft the pin 64 mounted one on i 6 and between the lower end of said shaft 86 and the inner face of said annular cap 85. Extending through the central 0 enlng of said. annular cap 851 and screws into the 8 lower end of said shaft 86 is the sleeve 88 which'carries at its lower and outer end the Said sleeve 88 has an annular flange 89. interiordiameter' substantially the same as the principal interior diameter of said hollow shaft 86. Said annular cap 85 carries on its lower side four osts 91 equally spaced from each other an mounted alon ilines extending downwardly and outwar ly the point on the axis of said "annular cap 85 the straps 92 span the ends of said posts 91 and are secured thereto by the screws 93.

On each of said posts 91 is slidably mounted a clamp jaw 95 each of which has formed therein a slot 96 which fits onto the adjacent portion of said flange 89 and which with 'said flange serves to hold the respective clamp jaws 95 in position with relation to each of the others. Extending through the bore of shafting 6 and sleeve 88 is the rod 97 which carries at-its inner end the s ring fits into the counter sink 99 formed at the lower e'xtremityof the bore ofsaid sleeve 88. At

chuck 98 the conical exterior of whic the upper extremity of said shaft 86 is formed a counter bore 100 concentric with the main bore of said shaft inwhich is positioned the tension spring 10]. positioned end on the washer 102 seated on the bottom of said counter bore 101 and at its upper end against the flange 103 fixed on said rod-97 whereby said spring 101tends to hold said chuck ,98 seated in said counter bore 99 whereby said chuck is held closed. The arinular (plug 104 screwed into the upper end of sai upper end of said rod'97 in its vertical move ment. The flange 105formed on .the upper endof said rod 97 serves as a seat for said lever 73 when the lever is pressed thereon by means of said belt or chain 75. The said spring 87 tends tomove sleeve 88 and shaft about said rod 97 and pressing at its lower counter bore 99 serves to guide the- 86 upwardly whereby-said-flange 89 carries distance of ,movement between the extreme open and extreme closed position by the distance of movement of said flange 89' and the angle of inclination of said rods 91 upon Wl'llCh said jaw clamps slide.

Rotational movement is imparted to said fires 2025 by means of said ulley 11 which is in turn actuated through the belt 110 passing over pulleys 111 through pulley 112 mounted on counter shaft 113 which in turn is drivenby the pulley 114 which connects therewith through clutch 115, said pulley '114 being actuated through belt 117 b a suitable motive Source not flshown. aid

clutch 1151s moved into and out of'engagement with said pulley 114 by means of the bell.crank 118, connected by rod 119 to-a' wheel 123 through" suitable gear in connec- .tion as is commonly known inthe'art. The

pipe line 125 connected by flexible hose 126 "to the. tabulation 127 of the hollow glass member 128 which isheld on the clamps of clamping table 121'serves to admit air uner pressure into the interior of said member 128 for the proper formation thereof when worked in the heat of said fires'2025.

The by-pass 130 connects said air supply.

pipe 125 to the interior of said lever handle 45 which is of pipe and therethrough-to the pipe 132 mounted thereon and termnating near said'bell crank 75. Sald 125 is of flexible material to allow for the movement of its connection to said lever .45.

In thefdrawings said chuck 98 and said clamp jaws 95are shown-{holding an anode chamber 140 and being fused to said chamber .128 which is the. main member. of a vapor. arc lamp, the body of said -\anode chamber 140 being held by said clamps 95 and the anode terminal 141 thereof held by said-chuck 98. l

. In the operation of the device of my 1nvention the hollow glass member 128 1s .sup-

being orted in clamps and aglass anode .cham-- er 140 is mounted between the clamping jaws 95 and the electrode 'lead -141"clamped between the jaws-of the spring .chuck 98. Said chuck- 98.1 and clamp (jaws 95 are .operated for thejopening an closing: thereof by 'nieansof bellicrank- .75 the handle of 1 which to open the -chuck and clamp pressed-toward thel elf handle 45, thereby drawing the lower. end I of chain 76* downe .wa'rd'ly" and so drawing lever 73 down againstksaid fiange 105 on the, upper end of rod 97 ivhei'eby said leverispushed down wardly against thefspring 1 101;. and: ;,the spring chuck 98 unseated from countersink .99 to-allow said chuck to spring open. Furither moi-'ement of said bell. crank 75 and.

Tubulation 127 is then consequently of lever 73 brings the latter against the top of sleeve 86'and causes it to move downwardly whereby said clamp jaws 95 pushed downwardly on rods .91 by flange :89 will 5 readapart. .Upon the release of hell cran $75 the springs 87 and 101'will cause clamps 95 and chuck-98 to, close on e chamber 140 and .on electric terminal 1 1 rim by closing the open end of th pipe which for example, being placed be tween the .clamps with the terminal 141 in the chuck will, upon such release,

be firmly held by said clamp and chuck.

A piece of tubing 128 closed at one end i of said tube 128 which is next said tubula- 126. By means of thehandle 123 the end tion 127 is moved with said bed plate 121 to a osition under the gas jet 150 which is fe proper operation 0 a suitable treadle operated valve notlshown a jet of flame from saidburner 150 is made to impinge on said end of tube 128 and when the propertemperature is reached such as is well known in the glass working art the glass, at the heated point is blown out'to form a s licing be 132 with a finger of the hand used foroperating lever 45 whereby pressure in the tube is caused to rise high enough to blow out the softened glass.

Bed plate 121 and tube '12s are then moved by 'handle' 123 until said blow out is ositioned under said anode chamber 140 by the su ply pipe 151.- Bythe he d by saidclamp comprising the jaws 95,

and the chuck 98 which latter by a backward movement of the lever 45 is brought into'position close to said blow out. Said fires 2Q, 25 are turned up from a'lowburning or] pilot ignition by meansof a'switch treadle operated valve not shown and b a backward movement of handle 46 said res 2'0, 25 are moved downwardly until the flames thereof impinge on the glass at said blow out and on the lower'end of the said anode chamber. By moving said anode chamber up and .down as desired through I lever 45, rotating fires 20, 20 by means of saidpulley 1 -14,'moving said fires 20, 20 up and'down by lever 46, and regulating the pressure .in tube 128 through varying the said tube 128 in a manner well known in the glass working art When such fusing is completed said anode chamber and the wire I sealed therethrough are released from chuck 'and'clamp 9598 by means of hand lever and the fires moved up by bringing'said no size of the opening in saidtube 132 with the. finger, the anode chamber 140 is fused to disconnected from flexible tube 126 and tube 128 replaced by a new one. Another anode chamber being inserted in chuck-clamp 95-1 repeated as before.
